Delight

• Persuade + Experience: personality may run through voice, composition, motion, and discovery, provided the artifact remains the focus.
• Operate + Read: concentrate delight at meaningful moments such as first use, completion, recovery, or mastery. Reliability carries everything else.

Find the opportunity

Inspect the target, DESIGN.md, product voice, repeated-use frequency, and emotional context. Look for:

• effort worth acknowledging;
• waiting that can become informative;
• an empty or first-use state that can orient;
• an error or recovery moment that needs empathy;
• an interaction whose physical or verbal response could express the brand;
• a useful capability people might enjoy discovering.

Do not manufacture a celebration for an ordinary click. Ask only when the brand’s emotional range or the stakes cannot be inferred.

Define one delight thesis

State in one sentence what the user should feel and why that feeling belongs to this product. Then choose the smallest system that can deliver it:

• a distinctive response to a meaningful action;
• product-specific language that clarifies while carrying voice;
• an interaction or transition with a recognizable material behavior;
• an illustration, sound, haptic, or environmental detail grounded in the product world;
• a discovery reward that reveals real utility.

Derive the treatment from product mechanism and visual world, not a stock catalog.

Build for the emotional moment

• Success: match the response to the effort and consequence. Major milestones can expand; routine saves should simply feel certain.
• Waiting: show truthful progress, useful context, or product-specific activity. Never fake work or delay completion to stage a flourish.
• Empty and first use: make the next action clear before adding personality.
• Error and recovery: lead with the problem and recovery. Warmth may reduce stress; jokes must not trivialize loss, money, privacy, or blocked work.
• Repeated interaction: keep the response satisfying after the hundredth use. Variation is useful only when it remains coherent and predictable enough to trust.
• Discovery: reward curiosity without hiding required functionality.

Copy must use the product’s language. Generic whimsy is worse than neutral clarity.

Protect the experience

Delight must not:

• delay, block, or obscure the primary task;
• override platform conventions or accessibility;
• add unrequested factual claims;
• play sound without consent or ignore mute settings;
• become mandatory, unskippable, or exhausting on repeat;
• add a dependency or asset cost disproportionate to the moment.

For authored motion, load animate.md. Respect screen readers, keyboard use, touch, localization, and cultural context. Nonessential loops stop when hidden. Make celebration intensity proportional to frequency and consequence.

Verify

• The moment is specific enough that a neighboring product could not use it unchanged.
• It improves comprehension, confidence, motivation, or emotional recovery.
• The interface remains fast and obvious without the flourish.
• Repetition does not turn charm into friction.
• Muted, keyboard, touch, and localized paths work.
• The result feels like the selected world, not a generic “delight” treatment.

When the personality feels earned, hand off to /impeccable polish for the final pass.
